So DNS response time lag for a visitor from China interrogating the GeoDNS node in the US is also negligible. DNS responses is cached for several minutes if not hours by local ISP resolvers so DNS "trips" are minimal. Regards Hi Maxim,

A question - Does this setup also handles DNS resolver proximity? Because if you DNS server sits in US but you try to resolve from China you still get degraded performance. Generally speaking: I'm personally intrigued to know how Akamai really works? Maxim. Hi, interesting setup.
